Pressure drop across the filter medium According to K-C equation the rate of filtration is proportional to the overall pressure drop across both the filter medium and filter cake. The pressure drop can be achieved in a number of ways: 17 Gravity • A pressure difference could be obtained by maintaining a head of slurry above the filter medium.

Removing, cleaning and replacing the damaged filter sand. Standard design practice of Rapid Sand filter: Maximum length of lateral = not less than 60 times its diameter. Spacing of holes = 6 mm holes at 7.5 cm c/c or 13 at 15 c/c. C.S area of lateral = not less than 2 times area of perforations.

The correction for pressure drop is shown in Figure 7 and can be calculated from Equation 5. As indicated, a higher pressure drop would result in a finer separation and lower pressure drop in a coarser separation. C 2 = 3.27 x 25% of the cyclone diameter to a maximum-0.28 (Eq. 5) Where C 2 = Correction for influence of pressure drop. = Pressure ...

Calculation for pressure filter design. Pressure sand filter is the first unit process in any treatment. It is used to remove suspended solids from raw water. Filter is designed based on velocity consideration. Recommended velocity for filtration is 10 m/hr to 30 m/hr. If we select velocity less than 10 m/hr, channeling will happen and velocity ...
